The SAGE Handbook of Research Methods in Political Science and International Relations offers a comprehensive overview of research processes in social science - from the ideation and design of research projects, through the construction of theoretical arguments, to conceptualization, measurement, and data collection, and quantitative and qualitative empirical analysis - exposited through 65 major new contributions from leading international methodologists. Each chapter surveys, builds upon, and extends the modern state of the art in its area. Following through its six-part organization, undergraduate and graduate students, researchers and practicing academics will be guided through the design, methods, and analysis of issues in Political Science and International Relations: Part One: Formulating Good Research Questions and Designing Good Research Projects; Part Two: Methods of Theoretical Argumentation; Part Three: Conceptualization and Measurement; Part Four: Large-Scale Data Collection and Representation Methods; Part Five: Quantitative-Empirical Methods; Part Six: Qualitative and Mixed Methods.
Chapter 18: Learning and Diffusion Models
Learning and Diffusion Models
In this chapter, we provide an overview of different methodological approaches used to study diffusion and learning. In political science, studies of diffusion seek to capture interdependence across units in the spread of an idea or action, such as the adoption of a policy by a state or country, the signing of compacts or treaties, the adoption of a norm of behavior, or the occurrence of political conflict. A variety of methods has been developed to understand how such items spread, each with its own advantages and disadvantages. We will highlight the theoretical foundations of diffusion research as well as the corresponding methodologies to understand how phenomena spread.
In American politics, diffusion research often focuses on ...
